【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、例えば食品容器内に窒素などの不活性ガスを
充填したり、あるいは、健康用酸素を袋状体に充填する
等のために、容器にガスを充填する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to, for example, filling a food container with an inert gas such as nitrogen, or filling a bag-like body with oxygen for health. , relates to a method of filling a container with gas.
従来、容器内に充填すべきガスを初めから気体状態で供
給していた。Conventionally, the gas to be filled into a container has been supplied in a gaseous state from the beginning.
しかし、容器が上部開放状態の場合、容器内へのガス供
給による既存ガスの排出を完全にすることは実質的に不
可能であり、充填ガスの純度が低くなりやすく、かつ、
ガスを加圧状態で充填することは不可能であった。However, when the top of the container is open, it is virtually impossible to completely exhaust the existing gas by supplying gas into the container, and the purity of the filled gas tends to be low.
It was not possible to fill with gas under pressure.
本発明の目的は、上部開放状態の容器にガスを高純度で
かつ加圧して充填できる方法を提供する点にある。An object of the present invention is to provide a method for filling a container with an open top with high-purity gas under pressure.
〔課題を解決するための手段］
本発明の特徴手段は、上部開放状態の容器内に低温液化
ガスを供給し、前記容器内において前記低温液化ガスの
蒸発により既存ガスを排出し、その後で前記容器を密閉
して前記低温液化ガスを封入し、その封入された低温液
化ガスの蒸発により前記密閉した容器内に加圧ガスを充
満させることにあり、その作用効果は次の通りである。[Means for Solving the Problems] The characteristic means of the present invention is to supply low-temperature liquefied gas into a container with an open top, discharge the existing gas by evaporation of the low-temperature liquefied gas in the container, and then The purpose of this method is to seal a container, fill it with the low-temperature liquefied gas, and fill the sealed container with pressurized gas by evaporation of the sealed low-temperature liquefied gas, and its effects are as follows.
つまり、上部開放状態の容器内にガスを低温液化状態で
供給して、容器内での低温液化ガスの蒸発によって容器
内の既存ガスを排出するから、低温で重いガスを確実に
容器に貯めて、既存ガスを容器から確実に排出させるこ
とができ、封入ガスの純度を十分に高くできる。In other words, the gas is supplied in a low-temperature liquefied state into a container with the top open, and the existing gas in the container is discharged by evaporation of the low-temperature liquefied gas within the container. This ensures that low-temperature, heavy gas is stored in the container. , the existing gas can be reliably discharged from the container, and the purity of the sealed gas can be made sufficiently high.
また、既存ガスを排出した後、容器内に低温液化ガスが
残っている間に容器を密閉し、密閉した容器内で低温液
化ガスを蒸発させるから、密閉した容器内の低温液化ガ
スの量を容器の容積などに見合って適当に設定するだけ
で、容器へのガス充填圧を広範に設定できる。In addition, after discharging the existing gas, the container is sealed while the low-temperature liquefied gas remains in the container, and the low-temperature liquefied gas is evaporated in the sealed container, so the amount of low-temperature liquefied gas in the sealed container can be reduced. The gas filling pressure into the container can be set over a wide range by simply setting it appropriately according to the volume of the container.
その結果、上部開放状態の容器にガスを高純度でかつ適
当な加圧状態で充填できるようになり、食品の無酸素包
装や健康酸素の製造等に便利な容器へのガス充填方法が
得られた。As a result, it has become possible to fill containers with open tops with gas at high purity and under appropriate pressure, creating a method of filling gas into containers that is convenient for oxygen-free packaging of foods and production of healthy oxygen. Ta.
